So presumably they'll be able to take another photograph in a year or two and the planet will have visibly moved? (Jupiter's orbital period around the Sun is about 12 years, but this planet is about 10 times further from the star and has an estimated orbital period of 550 years.)

Do NOT trust my napkin math, but I believe TWA 7 moves ~0.6 "pixels" (0.02 arcsec) per Earth-year.
